My battery is made of Sony VTC6
It works really good , even with full power, when the motors are cold
It it possible that I don’t have enough amp when my battery is around 35 V (after a ride - when motors are hot … )
Issues are just for start , when I ride it is ok
I don’t own a hub motor myself and have never have tried it but from my understanding they inherently get hot because the urethane covers up the motor instead of leaving it exposed for cooling like outrunners. The design of the Maytech hubs seem to confirm this in that the heat is being trapped and when there’s heat in your coils there’s more resistance, slowing you down. Other mainstream hubs like Meepo are integrated with the truck and have cone shape on the truck side for cooling as well as the truck helping dissipate the heat. Plus they’re limited to 35kph/22mph and tested at the factory to perform within these limits.
Also check the windings of the motor, a lot of times these motors rushed in mass production in China and the windings themselves are done poorly causing inefficiency. If you have enough money to spare I would recommend buying @Hummie hub motors. He hand winds them himself and checks that it is getting the right kv and is made of steel instead of aluminum. If you can wait there is also Carvon direct drives which you can choose your own wheel but that is pretty much unavailable because its only 1 guy producing it and he’s produced 25 in 8 months.
If I were you just go with belt driven or wait a couple more weeks for @Kug3lis to offer geared driven “direct” drives. Honestly this where the next level tech is.
If you do decide to remain in the hub motor game but just not Maytech hubs. Raptor 2 offers hub motors but that’ll cost you $800 per hub because they don’t sell standalone hubs. You’ll have to buy the complete then take apart the hub. You will have the best hub motors in the industry imo.
hi, thanks a lot for your reply.
i was looking for carvon hub / direct drive. I think it is the best solution for eskate : no pulley, no belt, but you can choose your wheels , …
i will try to fix issues on my maytech but I know that it is cheap quality…
It may be a hub motor thing cause my Raptor 2 does the same thing, when it’s hot or the battery is low usually both things are happening at the same time I get cut outs or cogging from a stop. Also brakes suck at high speed and they kick in hard at a lower speed
I found this thread from 2016. The hub motor looks like your Maytech ones. He had overheating problem when running an RC esc but when he switched to Vesc BLDC mode the motors ran cooler. Try running it in BLDC and see what happens.
Thanks for your reply
It seems to be a temperature issue. I will try to monitor motor temperature and I will check if I still have issue when I wait 20 min …
I will keep you informed. Thanks
